The number of seconds the Node Manager should wait before
restarting this server.

After killing a server process, the system might need several
seconds to release the TCP port(s) the server was using. If Node
Manager attempts to restart the Managed Server while its ports are
still active, the startup attempt fails.

If AutoMigration is enabled and RestartDelaySeconds is 0, the
RestartDelaySeconds is automatically set to the lease time. This
prevents the server from failing to restart after migration when
the previous lease is still valid.
